The Jena Experiment

The Jena Experiment is one of the longest running biodiversity experiments in Europe. The experiment is based on experiences from previous biodiversity experiments such as BIODEPTH or the biodiversity experiments (E120) in Cedar Creek in the USA. The Jena Experiment is funded by the Deutsche Forschungsgemeinschaft (DFG) in 2002. Plant diversity is manipulated on a 10ha field site nearby the Saale river within the city boundaries of Jena in Thuringia, Germany. More than 400 research plots have been established in a number of different experiments (see below). For the main experiment, plant communities of 1-60 plant species and 1-4 plant functional groups from a species pool of 60 species were sown on a former arable site. A main aim of the Jena Experiment is that a number of research groups are able to study ecosystem processes on the same plots, and over a time-scale of more than two years. Emphasis on particular effects of species is therefore reflected in different experimental designs in large as well as small plots.
